For when you need a brushless DC motor with push – and lots of it.
This linear actuator with an integrated high force bearing system, planetary gearing and brushless DC motor was recently on display at the oil and gas exhibition in Perth as an example of high force motor driven actuators for extremely harsh environments.

The European Conference on Space Debris recently highlighted an urgent need to start removing redundant objects out of orbit. Unless items are eliminated, collisions will be inevitable and space will become extremely hazardous. maxon motor uk has been working with the Surrey Space Centre (SSC) on their experimental solution.
The Surrey Space Centre‘s (SSC) drag deorbiting sail project, Inflatesail, contains two experimental structural components. The first is an inflatable rigidisable mast and the second is an ultra-lightweight polymer sail. The sail is supported by four custom manufactured ‘bistable’ carbon fibre booms which are wound around a central hub. maxon motor GP 16C planetary gearheads, combined with 16mm brushless DC motors from the maxon EC-max family, are used to drive and control the deployment of the booms. The ceramic components are wear and corrosion resistant for longer life and enable stability over a wide range of temperatures. The brushless DC motor and gearhead are fitted with high performance Braycote grease, which is non-flammable, suitable for extreme temperatures, is chemically inert and designed to be used in a deep space vacuum.
Dr Andrew Viquerat, Research Fellow at the SCC said ‚We have worked with maxon for a number of years, and continue to do so because of the reliability of the products. Some of our requirements are slightly unusual, and the people at maxon have been helpful and interested in helping us address them. In particular, we require DC motors which work in vacuum and at high temperatures.‘.
Gridweld Welding Systems has developed a new automatic pipeline welding crawler. This advanced unit uses online configurable DC motors from maxon motors DCX family.
Over the past decade, continual increase in energy demand coupled with strong development in the production of unconventionals and LNG (liquefied natural gas) has set solid grounds for growth in the onshore pipeline sector. Gridweld uses the latest technology to design and manufacture orbital welding systems. This specialised technique is used for joining pipes or tubes where the arc is rotated 360°. The West Midlands based company personnel have been involved in many pipe welding operations around the world. Since its development the welding bug Scorpion, has been used on projects within the UK, Ireland and Australia.
Mike Penny, Technical Director at Gridweld says ‚ We chose to work with maxon motor because of the high level of support and expertise available and the short delivery times available for the DCX.‘ Ian Bell, senior sales engineer from maxon motor said ‚The new DCX range has increased deliverable torque without increasing size or weight, both important deciding factors for Scorpion’s customers‘.

Hard to believe – but yes, maxon DC motors still running on the red planet after 10 years!
NASA rover Opportunity is still on its ground breaking exploration of Mars. The 39 DC motors that maxon motor supplied were originally designed to only last 3 months in the harsh environments have exceeded all expectations covering almost 40km.
All the way back in 2004 on this day, the 25th January, the DC motors received their first environmental exposure in Eagle crater. Since then the motors have gone on to propel the robot through countless territorial conditions, facing boulders, dunes, hills and flats on the search for evidence of water. With the ability to move soil, drill into stone and capture detailed images, the rover continues to supply vast amounts of information. It literally has a rocky past, it has been stuck in sand and battered by sandstorms creating major technical difficulties for NASA engineers. But despite this the DC motors survive even if the old girl is suffering a bit of “memory loss”. Thirty nine DC motors for thirty nine kilometres. Not just driving the wheels, maxon motors also control the manipulating arm, the rock grinding tool and vision systems. Based on standard maxon 20mm and 25mm DC motors they are over 90% efficient, even suffering the minus 120 to positive 25 degree environment.
